l Claim.

This invention relates to a bench vise and particularly to a universalbench vise adjustable around three axes at right angles to each other.

Among the more important objects of the invention are:

To provide in a bench vise an adaptor whereby a bench vise adjustablearound two axes at right angles to each other may be Converted into auniversal bench vise adjustable around three axes at right angles toeach other; to provide as an article of manufacture a bench vise adaptorper se; and to provide an improved combination of bench vise andadaptor.

A further object of the invention is to provide an improved bench viseadapted for use on drill presses and milling machines for betterenabling the operator to locate the desired angle at which holes are tobe drilled and surfaces machined.

Yet another object of the invention is to provide an improved bench visebetter adapted to meet the need of the Welders craft, wherein universaladjustment is an important factor. It is also an object of the inventionto provide a more compact and sturdy assembly of clamping structureswherein a succession of turnable parts are employed and are providedWith means for clamping them securely in the desired adjusted relationsto each other.

With the foregoing and other objects in view, the invention resides inthe novel arrangement and combination of parts and in the details ofconstruction hereinafter described and claimed, it being understood thatchanges in the precise embodiment of the invention herein disclosed maybe made Within the scope of that which is claimed without departing fromthe spirit of the invention.

Referring to the drawing, wherein is shown a preferred embodiment of theinvention as now reduced to practice, approved and being sold to thetrade,

Fig. l is a side elevation of a bench vise embodying my invention.

Fig. 2 is an end elevation thereof.

Fig. 3 is a plan view of the same partly in elevation and partly insection, on a larger scale.

Fig. 4 is a plan view of the adaptor per se.

Fig. is a section taken on line 5-5 of Fig. l.

Referring in detail to the drawing, the invention therein showncomprises a circular base I,

a primary divided yoke r, provided with a cylindrical bore 2a, swivellymounted on said base to rotate in a horizontal plane, an adaptor 3having a cylindrical stem 4 mounted in said bore 2a to rotate in avertical plane around the axis X-X, and a jaw assembly 5 having acylindrical stem 6 mounted in the cylindrical bore 'la of the dividedyoke 1 of said adaptor to rotate in a ver-y tical plane around the axisY-Y. The stem 6 of the jaw assembly is also interchangeable Within thecylindrical bore 2a of the divided yoke 2.

The cylindrical stem 4 of the adaptor is preferably constructed hollowas shown in Fig. 3, and the divided yoke I is circular with its curvedportion connected to the closed end of the stem 4 in an eccentric oroffset relation thereto with the axis of its bore la at right angles tothe axis of the stem 4. Around the stem 4 adjacent the juncture of theyoke with the stem 4 extends a laterally directed circumferential flange4a to abut against the peripheral face of the divided yoke 2 adjacentits counterbore and afford stop means to limit the insertion of the stemof the adaptor into the bore 2a.

Ears 8 are provided on the base I for securing the same to a bench, andthe yoke 2 is swivelly connected to the base by means of the cap screw 9and washer Ill. Clamp II secures the yoke 2 adjustably to the base Ithrough the medium of the clamping bolt I2, sai-d bolt being insertablethrough one or more openings I3 in the base and the head of the boltbeing movable in a complete circle within the widened bottom portion ofthe annular channel or groove I4 in the base. Said bolt is always in aneccentric relation to the axis about which the yoke 2 turns and affordsmeans for minute circumferential adjustment of the yoke.

The cylindrical yoke 2 is parted at I5 on one side and provided withcooperating ears I5 adapted to be drawn towards each other by means ofthe screw bolt I I so as to grip adjustably either the hollow stem 4 ofthe adaptor when it is used or the polygonally slotted stem 6 of the jawassembly when the adaptor is omitted.

The cylindrical yoke 'I of the adaptor is likewise parted at I8 on oneside and provided with cooperating ears I9 adapted to be drawn towardseach other by means of the screw bolt 2i) whereby to rmly gripadjustably the stem 5 of the jaw assembly.

With the polygonally slotted stem E is integralized the rear jaw cheek2I of the jaw assembly 5, said cheek having a polygonal slot whichregisters with the slot in the stem B to accommodate the polygonal stem22 of the front jaw cheek 23. Cheek 2| is also provided with acantilever arm 24 the better to support the jaw cheek 23 when the latteris outwardly projected by operating the screw 25 to move the grippingjaw 26 farther away from its jaw mate 21. Abutments 28 and 29, locatedat either side of the stem 22 and arm 24 and integral with the cheek 2|,further stabilize and strengthen the jaw assembly as a whole when theparts 26 and 2'1 are separated as aforesaid. The manner of operating thejaws 26 and 21 relatively to one another through the medium of the screw25 to grip a body being held therebetween, is a Way that is well knownand the description of which need not be repeated here.

By constructing the adaptor 3 (Fig. 4) with a hollow cylindrical stem atone end, said stem having a closed end with a peripheral flange 4aprojecting outwardly therefrom and providing a circular divided yokeattached to the closed end of said stem in the laterally oset mannershown in said Fig. 4, a right angular recess results which is bounded onone side by said closed stem end and on the other side by one of theopen ends of said divided yoke. This recess may be occupied by that partof the stem 22 of the movable vise jaw 26 which projects from said openside of said divided yoke thereinto, thus keeping said projecting stemfrom obstructing a clockwise movement of the jaw assembly 5 from thehorizontal position thereof shown in Fig. 2 to an upstanding position.This feature widens the range o f adjustability and yet retainscompactness.

What is claimed is:

A universal mounting for a base supported tool l0 comprising an adaptorhaving a longitudinally extending cylindrical stem adjustably supportedin the base, an outstanding circular flange at the base of thecylindrical stem to limit the insertion of the cylindrical stem into thebase support, a l5 reduced neck integrally formed with the base of thecylindrical stem and axially extending therefrom in an offset relationrelative thereto, and a split yoke integrally connected to the reducedneck portion and disposed with its opening at right angular relation tothe cylindrical stem, said split yoke having clamping means to retain aninserted tool in desired adjusted position.
